Package to allow user intervention

Hi

I need to create a package that will result in a message to a user, and the user will pass or fail the job based on what they get so that a further package can finish the process or not based on the user input

If anyone has done something similar can you tell what you did, and let me know any pitfalls?

Any help appreciated

Regards
